At IU, what is ezreset, and how can I use it to reset my accounts to their default settings?

About ezreset

On the Indiana University web servers Webserve and Mercury, the ezreset command launches a script that backs up copies of your configuration files and replaces them with the versions that are included with new accounts. These configuration files control the appearance, behavior, and general environment of your account. If problems arise with these files, you can use ezreset to replace them with working copies.

Using ezreset on Webserve

On Webserve, some login files will prevent you from running Unix commands. If you receive a "Command not found" error after entering a common command like ls or cd, use ezreset to restore the default settings.
